Gemini: dates, element, planet, symbolism and associated stones

Who is Gemini?

Gemini is the third sign of the zodiac. The symbol shows two standing twins, joined by two bars. In Greek mythology, one often sees the Dioscuri, Castor and Pollux, two inseparable brothers: one mortal, the other immortal, who chose to share their fate. The two bright stars of the constellation bear their names.

The image of doubling is ancient: it appears in several cultures of the Near East. This symbol of “two” explains why Gemini is called the sign of duality and of speech: at least two people are needed to hold a conversation.

The traditional profile at a glance

Gemini closes spring and leads toward the June solstice. The dates of the “tropical” zodiac, the one used in most Western horoscopes, vary by a day from year to year (leap years, exact time and place of birth). If you were born on the day the sun passes from one sign to the next, a birth chart calculated to the exact hour is needed to know which sign applies.

The tropical zodiac starts at the spring equinox and divides the year into twelve equal sections of 30 degrees. It no longer matches the position of the constellations in the sky, because of the precession of the equinoxes, a slow shift in the Earth's axis that completes one turn in about 25,800 years. The “sidereal” zodiac, used more in India, follows the constellations instead and therefore gives dates about three weeks later.

Element, modality and ruling planet

Air: the element of exchange, of ideas, of whatever circulates. Mutable: mutable signs end one season and prepare the next; tradition credits them with flexibility, adaptability and a taste for change. Mercury: the planet of the messenger, of trade and of speech; he rules Gemini as well as Virgo, in two distinct aspects: communication for Gemini, analysis and service for Virgo.

Symbolic qualities

Gemini is associated with curiosity, mental agility, humour, a love of wordplay, the ease of moving from one subject to another, and a knack for making contact. In traditional portraits, the reverse side is scattered attention, difficulty finishing what one starts, or sticking to a single opinion.

As with every sign, this is a caricature to be handled lightly. Many curious and talkative people were born under other signs, and people born under Gemini are also capable of silence. This portrait can only give you words to reflect on how you communicate.

Relationships with other signs

In astrology, the relationship between two signs is described by the angle that separates them in the zodiac. Here is the common vocabulary, applied to Gemini, with no prediction of compatibility whatsoever:

• Opposition (signs 180 degrees apart, six signs apart): Sagittarius. Astrologers see a face-to-face encounter that complements, a mirror.
• Trine (same element, air): Libra and Aquarius. People speak of a kinship of tone, an ease in understanding one another.
• Sextile (complementary elements): Leo and Aries. A link described as stimulating and sociable.
• Square (same modality, different element): Virgo and Pisces. Tradition sees a tension that either drives things forward or irritates.

These relationships are conventions for reading, not rules; astrologers themselves insist that one can get along very well with a sign that is “in tension” with one's own.

Stones traditionally associated

For Gemini, the traditions differ. Twentieth-century jewellery lists often cite agate; other esoteric writers propose citrine, tiger's eye or aquamarine, by analogy with the lightness of air. The lists linked to the stones of Aaron's breastplate do not agree with one another either.

Agate comes in many varieties, some of which are dyed; this is common and harmless if the seller says so. As for citrine, be aware that a large share of the citrines sold are heat-treated amethyst, a long-standing practice.

Mood ideas

A “Gemini” atmosphere is lively and varied: a shelf of books, a notebook for jotting down ideas, plants with light leaves, changing music, a corner for conversation. You could invite a friend to a card or board game, write a letter by hand, or keep a small journal of curiosities. Cards also make a good bridge: see the three-card spread tutorial. These are suggestions for mood, with no predictive value.

What science says

Scientifically, studies to date have not shown that the sign of birth makes it possible to describe a character or predict events. Astrology remains a symbolic and cultural language, which can be appreciated for its tradition and its poetry without being regarded as a science.
